Shinhwa’s members, all in their thirties, might lack the fancy moves of many boy bands nowadays, but they topped several local music charts last month with the album’s title song “This Love.” The album, released in May, marked the band’s return to the K-pop market after a year-long break.

While rival groups have long since fallen off the radar — that includes H.O.T and Sechs Kies, the two most popular boy bands in the late 1990s – Shinhwa has no immediate plans to retire. Fans hope they’ll last at least as long as popular J-pop band SMAP, which has been around for two decades.
